There is actually more space there than with the Edelbrocks.

I've never seen an e-head cut up but a KRE HP heads have good cooling between center exhaust bowls

If you care to do more testing on the quality of aluminium, send me a chunk of the head.. I will have our lab ( I work at an aluminium casting and exstrusion plant) run it through a bunch of tests...
I will send the results to you and you can do what you want with them..

That's awfully nice of you...I thought being nice was against your beliefs.

Thanks to Scott Roberts we have the tests back on the SpeedMaster Heads. I know not everyone can understand these results but what it comes down to is, as Scott states it, "Basically the aluminum is good quality A356".

Good material, good machine work, good price. Looks like a good head.

Good job, I hope you sell a bunch of them!

The tensile test put it right at the bottom scale of 6061 and top scale of A356..to be honest , I was surprised by the quality of the aluminium since it was Chinese.....

The Chinese have been infamous for dumping junk quality parts on the rest of the world. The same was true of vacuum tube production. If you wanted to see smoke from your electronics, a set of Chinese output tubes was sure to get the job done. They were even worse than the Russian consumer crap.

Once perestroika took effect, Russian tube manufacturers were forced to look for other clients, outside of their military. Turns out that Russian military tubes were very well built. Many of their tubes are interchangeable, or very close to European/American tubes. They have pretty much been the go-to guys for quality new production.

Someone finally convinced the Chinese to try making and selling a high quality line of tubes. they hired the right people from England, locally and elsewhere and now there are superb Chinese tubes to be had.

Psvane, Treasure, Genalex Golden Dragon are a few examples. They are not cheap, but they are high quality.

Bottom line is that the Chinese CAN make high quality parts for our consumption. Trick is finding the correct sources. Speedmaster has evidently done just that. I wish them well!
